In particular, disclosed is a compound that can be used as an HBV replication inhibitor and has the structure as shown in chemical formula (L), or a stereoisomer or tautomer thereof, or a pharmaceutically acceptable salt, hydrate or solvate thereof.

FIELD OF INVENTION

The present invention belongs to the field of medicine, and in particular, the present invention relates to a class of cyclic sulfonimidamide-arylamide compounds and the use as a medicine for treating hepatitis B thereof.

BACKGROUND OF THE INVENTION

Hepatitis B virus (HBV) is an enveloped virus of hepatotropic virus DNA family (Hepadnaviridae) with partially double-stranded DNA (dsDNA). The genome thereof contains 4 overlapped reading frames: precore/core gene, polymerase gene, UM and S genes (which encode three envelope proteins), and X gene. In the early stage of infection, the partially double-stranded DNA genome (open-loop DNA, rcDNA) in the host cell nucleus is transformed into covalently closed circular DNA (cccDNA) and transcribed into virus mRNA. Once encapsulated, the pre-genome RNA (pgRNA) (which encodes the core protein and Pol) serves as a template for reverse transcription, which regenerates this partial dsDNA genome (rcDNA) in the nucleocapsid.

HBV causes epidemics in certain areas of Asia and Africa, and is endemic in China. HBV has infected about 2 billion people worldwide, of which about 350 million people have developed into chronic infectious diseases. The virus causes hepatitis B disease and chronic infectious diseases are associated with a highly increased risk of development of cirrhosis and liver cancer.

The spread of hepatitis B virus is caused by exposure to infectious blood or body fluid, and the virus is detected in the saliva, tears, and urine of chronic carriers with high DNA titers in the serum.

Although there is currently an effective and well tolerated vaccine, the option of direct treatment is currently limited to interferon and the following antiviral drugs: tenofovir, lamivudine, adefovir, entecavir and telbivudine.

Additionally, heteroaryldihydropyrimidines (HAPs) are identified as a class of HBV inhibitors in tissue cultivation and animal models (Weber et al., Antiviral Res. 54: 69-78).

WO2013/006394 (published on Jan. 10, 2013) and WO 2013/096744 (published on Jun. 27, 2013) also disclosed sulfamoyl-arylamides having anti-HBV activity.

However, problems encountered in these direct HBV antiviral drugs are toxicity, mutagenicity, lack of selectivity, poor efficacy, poor bioavailability, and difficulty in synthesis.

Therefore, in order to overcome the above defects, it is necessary to develop HBV inhibitors with advantages such as high potency and lower toxicity.
